A new study has revealed that sales of smartphones worldwide rose significantly in the July to September period of this year to 169m – an increase of 47% in comparison with the same period in 2011.

The study – by independent research analyst firm, Gartner – claims that 1.83m smartphones are now purchased globally each day.

Gartner also revealed that sales of mobile phones in general during the same period stood at 427m – although it surmises that smartphones comprised the main impetus behind this figure, given that mobile phone sales overall were actually down by three per cent compared with the July to October period of 2011.

Looking closer at the data, Gartner says that while the smartphone sector continues to be dominated by Samsung, Apple and Nokia, market share between the three remains competitive.

Nokia, Gartner says, dropped its market share in the July to October period from 23.9% in 2011 to 19.2% this year – a decline of over 20%.

Samsung meanwhile saw its share of the market over the same period increase by 4.2% – whilst Apple’s share rose by 1.6%.

The biggest smartphone casualty in terms of loss of market share over this period was Blackberry from Research In Motion (RIM) – dropping 30 % year on year, according to the Gartner analysis, to a new low of just 2.1%.

Google’s Motorola Mobility meanwhile suffered a reduced share from 2.5% to 2% year on year.

Gartner found that the most popular operating system remains Android from Google – with the software being used in 72.4% of all smartphones sold, compared with 13.9% for iOS (Apple).
